Research on the Mechanism of How City Group Drive Economic Growth
Empirical Evidences from 16 Cities of Yangtze River Delta
Wu Fuxiang and Liu Zhibiao
(School of Economics of Nanjing University)
Abstract: In a city group , there is a significant positive correlation between urbanization rate and economic growth , and the
Yangtze River Delta city group is playing an increasingly important role as the new engine on economic growth , the empirical
results in the paper support this hypothesis. Yangtze River Delta city group drives economic growth mainly achieved through two
mechanisms : First , when elements are footloose among regions , some advantage elements prefer to gathering in large cities , while
the disadvantage elements prefer to gathering in small cities , which not only improve the urban agglomeration in the accumulation
of external economic factors and increase the urban agglomeration in the efficiency of research and innovation , but also promote
economic growth ; Second , when elements are also footloose among regions , governments prefer to selecting theTiebout Choice
mechanism efficiently and they enforce investment and the urban infrastructure construction within or among cities , and they try to
absorb the outer businesses and industries , which not only reduce transport costs of the enterprise , but also foster the circular
cumulative causality and the input2output linkages , thus it promotes the economic growth in the city group.
Key Words :City Group ; Economic Growth ; Tiebout Choice ; Input2Output Linkages ; Circular Cumulative Causality
